238 MANDIBULATA. — COLEOPTERA. 



embracing species both with 12- and 11-jointed antennae, and dif- 

 fering from each other in several particulars : all may, however, be 

 known from the Lamise and allied genera, by the form of the palpi, 

 added to that of the body, of which the thorax is cylindric and un- 

 armed, the elytra quadrate at the base, flat on the back, and in 

 general linear, or but little attenuated, and all the tibiae are simple. 

 In the first species the antennae are 12-jointed, the head narrowed, 

 and the general habit of the insect is different from that of the 

 genuine Saperdae : — in S. carcharias also the antennae and head are 

 also dissimilar to those of the other species ; and a third discordant 

 species appears to exist in S. oculata, in which again the antennae, 

 habit, and texture of the insect differ from the typical species.

Dw^j-brown, clothed with yellowish down: head small, elongate, narrow, with 

 a yellow longitudinal line on the crown : thorax obscurely rugose, with three 

 longitudinal yellowish lines, the central one being continuous with that on the 

 head: elytra rather coarsely punctate, irregularly sprinkled with minute 

 yellowish down, the shoulders a httle rounded, the apex gaping, and sHghtly 

 acuminated : scutellum yellow : antennae long, black, with the base of the 

 joints griseous-ash. 



Local : found abundantly in some parts of Norfolk, and in Hunt- 

 ingdonshire, in June ; but I believe not found in the immediate 

 neighbourhood of London. " Monk's-wood, Huntingdonshire, on
